In less than a minute, a business with a total amount of 1.3 billion yuan was finalized, and Wang Yufei was still very satisfied with this efficiency.

Of course, I am even more impressed by the penguins' wealth.

After all, there are not many companies that can take out more than 100 million in one breath and have no impact on daily operations. In fact, Changxiang Technology can also be regarded as one of them before, but since the beginning of promoting the construction of data centers, it is not good, not to mention more than a billion, hundreds of millions have to be saved.

After that, Ge Lingyue naturally arranged for the company's negotiators to discuss with Penguin's legal counsel, and the financial officers of the two companies would also work out the payment method that best suited the interests of the two companies.

Ge Lingyue is still doing a very good job in this piece.

For example, Changxiang Technology has been successfully rated as a high-tech enterprise supported by the state, and a lot of taxes can be saved every year, which is also one of the reasons why Wang Yufei has the confidence to build a large data center at this time.

Of course, there is a reason why Ma Huaide can be so refreshing.

For example, Penguin Group still wants to maintain a good relationship with Changxiang Technology.

What's more, although WeChat has added a function similar to co-production, whether the user experience can be compared to co-production still needs to be verified by the market. In particular, the co-production is a software developed for brain-computer chips, and the best understanding of brain-computer chips is naturally Changxiang Technology, and the Xin system, which has now begun to show a pandemic trend, is also a product of Changxiang Technology.

Let's not mention whether the two companies will sue because of the convergence of software, if Changxiang Technology really goes all out to operate the co-production, whether WeChat can resist the attack of the co-production, I don't think Ma Huaide has a score in his heart.

The deal also gives Wang more confidence in the future.

Sure enough, software development is really profitable.

Of course, the premise is to be able to scratch the itch of the other party.

It's as if the previous second system allowed Apple to throw 100 million dollars, and now co-production can make Penguin directly 1.3 billion.

In the future, if Changxiang Technology is really short of money, it is not impossible to consider developing some applications for the richest Internet companies in China.

Of course, it will not be sold to them directly, first developed and then launched, and after the market is accepted, the other party will most likely buy it at a premium for the sake of strategic layout.

For example, to develop a familiar chat software similar to WeChat, but more powerful and comprehensive than WeChat?

Well, wool is not good for a mammoth.

Develop your own VR technology, with the help of the brain-computer chip's radio wave sharing ability, develop an online shopping mall with an immersive experience?

That's right, after finalizing the 1.3 billion deal, Wang Yufei thought a lot for a while.

But because the brain works fast.

I thought a lot, but I almost always did it in an instant.

This also gives Wang Yufei a new vision for the development model of Changxiang Technology in the future.

A large software department was set up, with him personally serving as the technical director.

The large software department can refer to the previous concept of the brain-computer company and implement the intrapreneurship system.

As long as there are good ideas and ideas, you can get the company's internal investment, and become a project team to start research and development, and he can do some key technical guidance work next to him. After the results are obtained, they are quickly sold, and the funds obtained are returned to the company's investment, and after covering the cost of time and wages, the company and the project sponsor are distributed according to a certain proportion.

Well, how to do it still have to discuss it with Mr. Ge.

Ma Huaide would never have imagined that Wang Yufei was only silent for two or three seconds before he had already regarded him as one of the wronged leaders in his mind, so after Wang Yufei didn't speak for a long time, he took the initiative to say: "So happy cooperation!"

"Happy working together!"

"Tomorrow I will ask the group's legal department to draw up a rough contract. ”

"Well, when the time comes, contact Mr. Ge directly, and she will arrange it. ”

"Well, goodbye. ”

"Mr. Ma, goodbye!"

......

Hanging up the phone, Ma Huaide was sullen for a while.

But a year ago, the guy on the other end of the line was just a high school student.

If his plan to seek talents at that time can succeed and pull Wang Yufei into the penguin, it means that whether it is a brain-computer chip, a Xin system, or a co-production, the penguin will be able to get a piece of the pie.

It's not just a piece of the pie, maybe it's all the penguin industry.

This made Ma Huaide begin to suspect that he still didn't seem to pay enough attention to this young man at the beginning.

I just tried it once, and I went to Star City in person, and the invitation was gone.

Or he should learn from Liu Bei's Sangu Thatched House, and with enough sincerity, maybe he can impress Wang Yufei, who was still studying at the time.

It's just that it's too late to say anything.

Enjoy Technology is now a well-known technology company at home and abroad.

As the market matures, the valuation of brain-computer chips and Xin systems is increasing exponentially every day, and now even if Wang Yufei agrees, it is not so easy for Penguin Group to acquire Changxiang Technology.

For a while, a lyric appeared in Ma Huaide's mind.

"Some people, once they miss it, are not there. ”

......

The capital has a temperate monsoon climate.

Summers are hot, winters are cold, and the climate is dry with very little rain.

Late spring and early summer evenings are probably the most suitable time for outdoor walks.

In addition, in recent years, the state attaches great importance to the environment, and the haze problem that has been plaguing the capital has also improved a lot.

The campus environment is quiet, the building is simple, and there are no tourists at night, the environment is quiet, especially suitable for love.

A business of 1.3 billion yuan has somewhat made the dating atmosphere fall into clichés.

Fortunately, neither of them cared much about the brief interruption.

However, it made Lu Yuxin more interested in the reaction on the Internet, and it happened that the two had already walked to the lawn outside Huaqing School, so Lu Yuxin simply pulled Wang Yufei to sit back to back on the lawn, and looked at the mobile phone intently.

This small square is only separated from Huaqing Pond, a scenic spot on the Huaqing campus, by a two-story building.

However, Wang Yufei's eyes unconsciously fell on a stone tablet with a sense of age in the northeast corner of the lawn, and the top is a row of small characters, the Beijing City Cultural Relics Protection Unit, the early building of Huaqing University, and the time when this stone tablet was erected is also recorded below, October 1990.

Ninety?

His parents seemed to be just adults at the time.

It's easy to immerse yourself in nostalgia for something historical.

It's a pity that Wang Yufei in his childhood doesn't seem to think of anything that he misses.

For a while, the brain was a little empty.

The equations that had been recorded on the shores of the unnamed lake flooded back into his mind.

Then Wang Yufei once again felt the beauty of mathematics.

A quote from Russell's history of Western philosophy that came to mind unconsciously came to mind: "Mathematics not only contains truth, but also expresses the highest beauty—a beauty that is calm and simple, like a sculpture, which does not appeal to any of our weak natures, does not appeal to the magnificence of painting or music, but is pure and solemn, and only the greatest art can show its strict perfection." ”

Wang Yufei felt this deeply.

A series of equations slipped through his mind, and Wang Yufei unconsciously stretched out a finger again to write and draw on the grass.

During this time, the study of quantum algorithms seems to fit in with the complex equation in my mind.

If his previous inference is correct, the straight line in this universe is just a pseudo-concept of counter-intuitiveness, any line has curvature, and can only be infinitely close to the remaining straight line, but it can never be a straight line, then the upper limit of curvature is probably the periphery of this universe.

Because it is large enough, any segment taken is infinitely close to the solid line.

And all matter in this space will follow certain rules.

The state of the universe is not determined by all the particles in the universe with their positions and velocities, or the state of motion, but by the mathematical object of the wave function at this stage. But according to Schrödinger's equation, the wave function evolves over time in a uniform manner.

To put it more simply, the wave function is constantly evolving in the infinite dimensional space of Hilbert space, and although the quantum motion is random, unpredictable, and uncertain in the process, the wave function itself evolves in a completely deterministic way, without the slightest randomness at all.

These ideas are a bit of a mouthful.

There seems to be some contradiction between the uncertainty of the movement of a single quantum itself and the uniqueness of the way it evolves in the general direction.

Unless everything can be unified by a formula.

Wang Yufei's thoughts suddenly drifted away, and another idea broke into his mind.

"Yu Xin!"

"Huh?"

"Do you think there really be such a thing as a space-time machine in this world, or will it really be possible to create a space-time machine in the future?"

"Why did you suddenly think of this?"

A question suddenly came to mind. Suppose we have a dice in our hand, the most ordinary of the six sides, and during the time it is thrown, it will be a superposition of six sides. Because we don't know which side is on top when it stops. But in our space, when it stops, it is already established that there will only be one side up, and not all six at the same time. ”

"At this time, we imagine a higher-dimensional space, if we put this dice into this high-dimensional space, when we start throwing it, what will happen? Is it possible that there will be a state where six sides are facing up at the same time? After the result appears, after taking this dice back to our low-dimensional space, the dice will naturally not be able to maintain the form of six sides facing up at the same time, then each side may come into contact with a space, which I call the high-low dimensional transformation. ”

Although Wang Yufei, who was in a mysterious mood, described it very vaguely, and it could even be said that he did not find the point, Lu Yuxin still grasped the key point very keenly.

"High- and low-dimensional transformations, you mean parallel universes?"

A high-dimensional world can be decomposed into several low-dimensional worlds, just as a two-dimensional surface can be decomposed into several one-dimensional lines, a three-dimensional body can be decomposed into an infinite number of faces, and a higher-dimensional space can naturally be decomposed into multiple three-dimensional spaces. Generally speaking, whether it is to send matter from a low-dimensional space into a high-dimensional space, or from a high-dimensional space back to a low-dimensional space, it takes a lot of energy to complete. ”

"Okay, so what does this have to do with the time machine you talked about?" Lu Yuxin asked again very cooperatively.

The girl knows very well that sometimes the right questions can make the thinking line clearer.

"It's very simple, do you say that it is possible that a civilization of the same kind that is more advanced than us has created a space-time machine because of some kind of difficulty. I want to travel back in time and change history. But it is impossible to travel through time and space itself, and the so-called space-time machine is actually a dimensional transition technology. The space-time machine first jumped into the higher dimensions, and then re-entered the lower dimensional world after a short stay. ”

"The pre-set coordinates are actually the earth with different development processes of countless parallel worlds, which means that the so-called space-time coordinates are the coordinates of a high-latitude space to the dimensional space. Time is actually a pseudo-concept, but in a high-dimensional space, it corresponds to the coordinates of a low-dimensional space?"

Lu Yuxin was a little bored, and after a while, she spoke: "Classmate Wang Yufei, do you want to talk about the story of a person who traveled from the future world to our era and then planned to destroy the world or transform the world?"

Wang Yufei didn't say anything, and corrected in his heart: "This is probably one such story." An old grandfather who came to Earth from another plane, met him, and then injected him with something that he doesn't know, modified his brain and body to the greatest extent, and imprinted some understanding of their understanding of technology and research results in his mind through some kind of biological agent, and hoped that he could locate their world to save their story?"

Well, Wang Yufei can only guess about this issue.

The old man he met that morning did not leave him with obvious clues to know these true truths.

Of course, it is also possible that the clues are contained in the imprint in his mind, but they have not yet been stimulated.

But after thinking about it, Wang Yufei didn't think that he could really design something as obviously contrary to common sense as a time machine.

Of course, even if it is designed, with the current level of industrial manufacturing on the earth, it is likely impossible to produce it.

But these equations just now have a great enlightening effect on the quantum superbrain he needs.

At the heart of quantum computing lies in its quantum coherence.

All he needs to test is the motion of the finite-dimensional Hilbert space quantum coherent states in the equation.

If the equation is correct, then theoretically there is a theoretical guide for the design and fabrication of a general-purpose quantum computer.

And then......

"Alright, don't think about all this stuff, Google has challenged you. ”

"Huh, what challenge?"

Lu Yuxin didn't answer, but directly stretched out her hand and handed the phone to Wang Yufei from above.

Wang Yufei raised his head slightly, and his eyes were the Weibo interface that he was just familiar with today.

The high-tech company Weibo, which has not yet passed 24 hours after the press conference, has dedicated @ him.
